IMPROVEMENT iN CARPET-BEATERS.

Specification forming part of Letters Patent No. 116,958, dated July 11, 1871.

To all whom it may concern:

Be it known that we, JAMEs HOTHERsALL -part of this specification, in which drawing- Figure 1 represents a plan or top view of this invention. Fig. 2 is a side view of the same. Fig. 3 is a vertical section of the same taken in the plane m a', Fig. l.

Similar letters indicate corresponding parts.

This invention consists in the arrangement of a series of beaters secured to the outer ends of elastic arms and actuated by revolving tripwheels, said beaters being situated over a iieX- ible platform composed of cords or ropes, over which the carpet is drawn by suitable feed-rollers, and under which are situated two brushes, one in front and the other behind the beaters, in such a manner that, by the revolution of one shaft, the carpet is slowly fed along imder the beaters, while-the beaters receive a rapid vibrating motion, acting on the carpet with good effect, and at the same time the carpet is exposed to the action of the brushes, one of which has arevolving and the other a vibrating motion, and thereby a carpet can be cleaned in a comparatively short time and without danger of sustaining any injury.

In the drawing, A designates a frame which is made of wood or any other suitable materia-l. On one end of this frame is situated the drivingshaft B, which connects by gear-wheels a b with a secondary shaft, c, on which is mounted a series of trip-wheels, d. These trip-wheels act on levers e, which connect by rods fand belts g with the beaters C. The belts g run over pulleys g in the top part of the frame A, and the beaters are connected to the outer ends of arms h, made of wood or other elastic material and retained at their backV ends by hooks i and cross-bars j. 'Vhen the beaters are raised, therefore, the arms IL are bent, and whenever one of the trip-wheels releases its lever the. vcorresponding beater is carried down by the elasticity of its arms, and it inflicts a smart blow to the carpet situated beneath it. The carpet, while being acted on by the beaters C is supported by a flexible platform, D, formed of cords or ropes which are secured in one side of the frame A and strained bythe action of a windlass, E, secured to the opposite side of said frame, as shown in Fig. l of the drawing. A ratchet-wheel and pawl serve to retain the windlass in position when the ropes of the platform D have acquired the required tension. The back ends of the beater-arms are supported by a beam, F, resting on arms extending from the frame A, so that the carpet can be drawn through beneath said beam and between the iieX- ible platform D and beaters C. (See Fig. l.) The requisite feed-motion is imparted to the car pet by rollers G, with a soft or elastic surface, so that they a-re able to take a firm hold of the carpet without injiuing the same. Said feed-rollers are geared together by cog-wheels 7c, and they receive the requisite motion by means of a belt, l, ex-

tending from a pulley on the end of the trip-wheel shaft over another pulley mounted on the end of the shaft of one of the feed-rollers. Below the flexible platform D are two brushes, H I, one in front and the other behind the beaters C. The front brush l receives an oscillating motion by an eccentric moiuited on the inner end of the driving-shaft B, and connected, by a rod, m, with an arm, a, extending from a rock-shaft, o, on which said brush is mounted. The rock-shafto has its bearings in the sides of the frame A, and by its action the motionimparted to the brush I is similar to that of a brush operated by hand, and the dust adhering to the siu'face of the carpet, after the same has passed the beaters, is eifectually removed. The back-brush H receives a revolving motion imparted to it by a belt, p, extending from a pulley 011 the driving-shaft over a pulley on the shaft of said brush, and by the action of this brush the dirt adhering to the surface of the carpet before it passes through under the beaters is scraped off. Beneath the ilexible platform D v is a dust-receptacle, J, and if the frameA is wel] covered up while the machine is in operation the largest portion of the dust collects in said receptacle.

By this machine carpets of all sorts can be cleaned with the greatest ease and facility, all

dmger of injuring the carpet is avoided, and the 2. The oscillating front brush I and revolving carpet passes through the machine without rebeek brush H, in combination with the rigid bezitquring any attention. ers C, flexible platform D, and feed-rollers G,

What We claim as new, and desire to secure by substantially as set forth.
